FIELD OF THE INVENTION

The present invention relates to a wearable electronic device, and more particularly, to a wearable electronic device having an interface for electronic communications.

BACKGROUND

Mobile computing devices, such as mobile phones, are increasingly prevalent. As additional functions are developed for mobile computing devices, users spend more time using the devices. Known mobile computing devices, however, require a user to look at and interact with a screen in order to use the mobile computing device. Although mobile computing devices are useful in a wide range of applications, the increasing amount of time spent looking at the screen of mobile computing devices detracts from social encounters and also diminishes other interactions of the user with his environment. Mobile computing device users have a need to easily and intuitively utilize the benefits of the mobile computing device without spending large quantities of time looking at the screen.

SUMMARY

A wearable electronic device comprises a ring body defining an annular receiving space within the ring body and a substrate disposed in the annular receiving space. The ring body has an interface disposed on an exterior of the ring body. The substrate has a plurality of capacitive plates positioned proximate the interface.

DETAILED DESCRIPTION OF THE EMBODIMENT(S)

This description of the exemplary embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description. In the description, relative terms such as “lower,” “upper,” “horizontal,” “vertical,”, “above,” “below,” “up,” “down,” “top” and “bottom” as well as derivative thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation. Terms concerning attachments, coupling and the like, such as “connected” and “interconnected,” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise.

In FIGS. 1 through 6, like items are indicated by like reference numerals and, for brevity, descriptions of a component or structure are not repeated. Materials describing the manufacture of a component in one description can be used to manufacture that component in each embodiment unless specifically stated otherwise.

The present disclosure provides an apparatus comprising a piece of jewelry connected with an interchangeable radio frequency identification (RFID) tag. The apparatus is provided to enable a user to conveniently and unobtrusively carry a RFID tag with a low probability of loss or damage to the tag.

In some embodiments, the jewelry piece is a ring. However, other jewelry pieces would be suitable for use in accordance with the present disclosure. Specifically, the present disclosure could be used to connect an interchangeable RFID tag with watches, pendants, brooches, earrings and other body piercing jewelry, necklaces, bracelets, amulets, medallions, hairpins, and any suitable jewelry pieces.

There are generally three types of RFID tags: active, passive, and battery-assisted passive. In some embodiments of the present disclosure uses a passive tag, which is generally cheaper and smaller than active or battery-assisted passive tags because it requires no independent power source. A passive tag uses the radio energy transmitted by a RFID reader as its power source. However, any type of RFID tag would be suitable for use with the present disclosure. Use of an active or battery-assisted passive RFID tag requires the addition of an independent power source such as a battery to the disclosed apparatus. The active RFID tags embodied in this disclosure are additionally capable of low- or reduced-power modes. In this disclosure, an RFID tag is not necessarily limited to any specific operating frequency. An RFID tag useable with the present invention may also operate with either regulated or unregulated frequencies.

FIG. 1 is a side view of one example of a jewelry piece 100 with an interchangeable RFID tag in accordance with some embodiments of the present disclosure. FIG. 1 shows the exterior of the apparatus with all component pieces assembled. Viewing the exterior, a user or viewer of the apparatus sees a cap 2, a housing 14, and a ring 16, which are described in further detail below.

FIG. 2 is a schematic exploded side view of an example of a jewelry piece 100 with an interchangeable RFID tag in accordance with some embodiments of the present disclosure. FIG. 2 illustrates how constituent pieces of the apparatus are fitted together in the illustrated embodiment.

Cap 2 is formed from a gemstone, a synthetic or imitation gemstone, or like material including glass or plastic. Cap 2 is often formed as a “cabochon” having a convex, substantially hemispherical surface and a flat surface. In the alternative, the cap can have a concave surface and a flat surface. The shape of cap 2 can vary, employing any suitable gemstone cutting techniques. Cap 2 is connected to housing 14 by cement, glue, solder, or other suitable adhesive.

Below cap 2 is a RFID tag 6 which may be of any suitable type and configuration but is illustrated as a RFID wafer. RFID tag 6 is disposed within a buffer ring 8. In some embodiments, buffer ring 8 is composed of a ferrite material. Buffer ring 8 is disposed within housing 14. RFID tag 6, buffer ring 8, and the inner diameter of housing 14 are sized to minimize movement of the RFID tag 6 during use of the apparatus.

In some embodiments, the jewelry piece 100 includes one or both of a top spacer 4 and bottom spacer 10 to further minimize movement of RFID tag 6 during use. In some embodiments, top spacer 4 and bottom spacer 10 are composed of a material that does not substantially inhibit radio frequency transmission such as plastic or glass. A material does not substantially inhibit radio frequency transmission if the transmission range is not notably reduced by using that material. Materials that do no substantially inhibit radio frequency transmission, such as glass and plastic, are substantially permissive materials.

In some embodiments, top spacer 4 and bottom spacer 10 are composed of materials which inhibit radio frequency transmission, such as most metal alloys, as a way to limit the range of enclosed RFID tag 6. For example, if RFID tag 6 is readable from a distance of three feet from a jewelry piece 100 without top spacer 4 or bottom spacer 10, but if it is desired that RFID tag 6 only be readable at a distance of six inches from jewelry piece 100, then one or both of top spacer 4 and bottom spacer 10 may comprise a material which inhibits radio frequency transmission, which may be added to jewelry piece 100 to reduce the effective reading range of RFID tag 6. In some embodiments, the range of RFID tag 6 may be limited by the structure of RFID tag 6 or may be limited by programming. Also, spacers may not be necessary to limit the range but may be desired nonetheless to immobilize the contents of jewelry piece 100.

The unit formed by cap 2, RFID tag 6, buffer ring 8, and housing 14, when connected, is referred to as a command module 20. In some embodiments of the present disclosure, command module 20 is fully interchangeable, meaning a first command module connected to ring 16 can be removed and replaced with a second command module.

Housing 14 is formed from stainless steel, precious metal (gold, silver, platinum, and the like), or any suitable material for forming jewelry, such as carbon fiber or titanium alloys. Housing 14 is sized to fit within a receiving area 18 of ring 16. Housing 14 is connected to ring 16 by a screw post 12, which is a threaded member that is rotatably inserted into a threaded slot 22 in ring 16.

Ring 16 is formed from stainless steel, precious metal (gold, silver, platinum, and the like), or any suitable material for forming jewelry, such as carbon fiber or titanium alloys. In some embodiments, ring 16 may be formed from various insulating materials such as ceramic, nylon, acrylic, Lexan, Lucite, or the like, which provide non-radio wave interference properties, allow for low cost of production, low weight, improve esthetics, and can be easy to remove in an emergency.

In some embodiments, a ring formed from ceramic or similar material is given the appearance of a precious metal or other metal through chemical vapor deposition of a metal coating on the exterior surface of the ring. In other embodiments, a ring formed from ceramic or similar material is given the appearance of a precious metal or other metal through ionic beam subsurface deposition of metal below the exterior surface of the ring. Such embodiments have the advantage of appearing as metal rings while having minimal RF interference due to their ceramic construction.

Ring 16 includes a receiving area 18 and threaded slot 22 for receiving housing 14 and screw post 12, respectively. Housing 14 and ring 16 can be formed from the same material or different materials.

FIG. 3 is a schematic top view, with components again exploded as in FIG. 2, of a jewelry piece with an interchangeable radio frequency identification tag in accordance with some embodiments of the present disclosure. As in FIG. 2, FIG. 3 illustrates how the constituent components of jewelry piece 100 are fitted together. In the illustrated embodiment, RFID tag 6 is disposed within buffer ring 8, which in turn is disposed within housing 14 along with top spacer 4 and bottom spacer 10. Cap 2 is adhered to housing 14 to form command module 20. Command module 20 is operatively connected to ring 16 via a screw post 12 (not visible in FIG. 3) rotatably inserted into threaded slot 22.

Referring now to FIG. 4, in some embodiments, cap 40 comprises a top 42 connected to a threaded member 44 which can be rotatably inserted into a threaded recess 46 on ring 48. Top 42 is formed from a gemstone, a synthetic or imitation gemstone, or like material including glass or plastic. Top 42 is adhered or mounted to threaded member 44. A RFID tag 6 is disposed within a buffer ring 8, which is then disposed within threaded recess 46. Cap 40 seals RFID tag 6 and buffer ring 8 within the threaded recess 46 when rotatably inserted into the threaded recess 46. In some embodiments, one or more spacers can be included on either side of RFID tag 6 disposed within buffer ring 8. The one or more spacers can be either substantially permissive or substantially inhibiting, as described above.

In the embodiment shown in FIG. 4, ease of access to an enclosed RFID tag provides another means of interchangeability. In some embodiments, rather than changing out the entire command module 20, a user can unscrew cap 40 from ring 48 to remove cap 40, permitting access to and exchange of the enclosed RFID tag 6.

In some embodiments, shown in FIG. 5, the command module 20 is affixed to a modified ring 52 via a retaining clip 50. Retaining clip 50 is shaped to fit about the bottom of housing 14, and has a bulbous protrusion 56 on one side. Retaining clip 50 can also be a standard “C” clip. Once retaining clip 50 is connected to housing 14 using adhesive or simple friction, the entire command module 20 is slid into position, mounted on modified ring 52. The bulbous protrusion 56 is fitted into a groove 54 on modified ring 54, and command module 20 snaps into place on modified ring 52 where it is held by the union of bulbous protrusion 56 and groove 54. In some embodiments, one or more spacers can be disposed within command module 20, on either side of RFID tag 6 disposed within buffer ring 8. The one or more spacers can be either substantially permissive or substantially inhibiting, as described above.

In some embodiments, shown in FIG. 6, a hollow cap 60 is used to hold the RFID tag instead of the previously-described housing. As with previously-described cap 2, hollow cap 60 is formed from a gemstone, a synthetic or imitation gemstone, or like material including glass or plastic. Also, hollow cap 60 has a convex, substantially hemispherical surface and a flat surface. In the alternative, the cap can have a concave surface and a flat surface. Hollow cap 60 has a recess formed in the flat surface to hold an RFID tag 6 and buffer ring 8. In the illustrated embodiment, RFID tag 6 is disposed within buffer ring 8, which is then disposed within hollow cap 60. Hollow cap 60 is then affixed to a bezel setting 62 or similar plate, which has a screw post 66 that is rotatably insertable into a threated slot 68 in ring 64. In some embodiments, one or more spacers can be included on either side of RFID tag 6 disposed within buffer ring 8. The one or more spacers can be either substantially permissive or substantially inhibiting, as described above.

In some embodiments, shown in FIG. 7, a ring 72 has a channel 74 through its top portion. In some embodiments, the channel 74 is cylindrical and includes a notch 76 cut the full circumference of the channel 74. Channel 74 is sized to hold RFID tag 6 disposed within buffer ring 8. Notch 76 is sized to hold bottom retainer 78 in place. Bottom retainer 78 is formed from a flexible material, such as semi-rigid plastic, so it can be inserted and removed from notch 76. The diameter of bottom retainer 78 is larger than the diameter of channel 74 but smaller than the diameter of notch 76, allowing bottom retainer 78 to be held in place when inserted into notch 76. With bottom retainer 78 inserted into notch 76, buffer ring 8 and RFID tag 6 are disposed within channel 74 and sealed in place by cap 79.

Cap 79 may be connected to ring 72 by cement, glue, solder, or another adhesive.

As with cap 2, cap 79 is formed from a gemstone, a synthetic or imitation gemstone, or like material including glass or plastic. Also, cap 79 defines a convex, substantially hemispherical surface and a flat surface. In an alternative embodiment, cap 72 may define a concave surface and a flat surface.

In some embodiments, bottom retainer 78 is formed from a material that is substantially permissive of radio frequency transmission and cap 79 is formed from a material that substantially inhibits radio frequency transmissions. In this embodiment, the effective transmission range of RFID tag 6 is greatly limited.

In some embodiments, shown in FIGS. 8A and 8B, a jewelry piece 89 comprises an annular body 82 having a channel 74 with a protruding edge 83 that retains elements disposed within channel 74. When disposed within channel 74, cap 86 is prevented from exiting channel 74 by protruding edge 83. Cap 86, RFID tag 6, buffer ring 8, battery 84, and bottom retainer 78 are loaded from inner side 87 of channel 74 and retained on outer side 88 of channel 74 by protruding edge 83. In some embodiments, channel 74 may be cylindrical and include a notch 76 cut the full circumference of channel 74. Channel 74 may be sized to hold RFID tag 6 disposed within buffer ring 8. Notch 76 is sized to hold bottom retainer 78 in place. Bottom retainer 78 is formed from a flexible material, such as a semi-rigid polymer, so it can be inserted and removed from notch 76. The diameter of bottom retainer 78 is larger than the diameter of channel 74, but smaller than the diameter of notch 76, allowing bottom retainer 78 to be held in place when inserted into notch 76. With bottom retainer 78 inserted into notch 76, buffer ring 8 and RFID tag 6 are disposed within channel 74 and held in place by cap 86. As with cap 2, cap 86 may be formed from a gemstone, a synthetic or imitation gemstone, or like material including glass or plastic. Also, cap 86 may define a convex, substantially hemispherical surface and a flat surface. In alternative embodiments, cap 86 may define a concave surface and a flat surface. In some embodiments, bottom retainer 78 may be replaced with a retaining clip such as retainer clip 50 described above. In some embodiments, battery 84 is omitted and RFID tag 6 may comprise a passive-type tag. In other embodiments, spacers (not shown) are used to ensure RFID tag 6, buffer ring 8, and battery 84 remain immobilized during use. In some embodiments, additional RFID tags are disposed within channel 74; multiple RFID strips are used to increase functionality or security of jewelry piece 89.

Referring to FIGS. 9A, 9B, 9C, and 9D, a ring 90 comprises two raised edges 92 defining a channel 94. A printed RFID strip 96 and decorative cover 104 are disposed within channel 94. In some embodiments, a battery 102 may also be disposed within the channel and operatively connected to RFID strip 96. Ring 90 is formed from stainless steel, precious metal (gold, silver, platinum, and the like), or other materials suitable for forming jewelry, e.g., carbon fiber or titanium alloys. In some embodiments, ring 90 may be formed from various insulating materials such as ceramic, nylon, acrylic, Lexan, or the like, which provide non-radio wave interference properties, allow for low cost of production, low weight, improve esthetics, and can be easy to remove in an emergency.

In some embodiments, a ring formed from ceramic or similar material is given the appearance of a precious metal or other metal through chemical vapor deposition of a metal coating on the exterior surface of the ring. In other embodiments, a ring formed from ceramic or similar material is given the appearance of a precious metal or other metal through ionic beam subsurface deposition of metal below the exterior surface of the ring. Such embodiments have the advantage of appearing as metal rings while having minimal RF interference due to their ceramic construction.

Ring 90 comprises an inner surface 106, an outer surface 108 defined by the top surfaces of raised edges 92, and a channel bottom surface 110. In some embodiments, ring 90 is annularly shaped. RFID strip 96 comprises a flexible substrate or semiconductor which includes at least one memory chip 98 and an antenna 100. In some embodiments, RFID strip 96 includes at least one RFID tag which may be of any suitable type and configuration such as a RFID wafer. In some embodiments, RFID strip 96 includes a printed, flexible CMOS integrated circuit. In some embodiments, battery 102 may be constructed from flexible materials, such as a flexible lithium or graphene battery. In some embodiments, additional RFID strips are disposed within channel 94; multiple RFID strips are used to increase functionality or security of ring 90.

Decorative cover 104 is dimensioned to fit into channel 94, and formed from a gemstone, a synthetic or imitation gemstone, or like material including glass or plastic. In some embodiments, decorative cover may be formed from a thermo-reactive material which changes color based on temperature. Decorative cover 104 may take many shape suitable for decorative and functional purposes. In some embodiments, decorative cover 104 may be connected to raised edges 92 by cement, glue, solder, or other suitable adhesive. In other embodiments, decorative cover 104 may be connected to raised edges 92 by friction fitting. In further embodiments, an exterior surface 112 of decorative cover 104 may be seated flush with outer surface 108 of ring 90. In yet further embodiments, decorative cover 104 may be formed over RFID strip 96 and battery 102. In many embodiments, decorative cover 104 is operatively connected to battery 102 and comprises solar power cells to charge the batter 102 with solar-generated electricity. In some embodiments, decorative cover 104 includes LED panels which are configured to display information to a user. For example, the panels may be configured to display messages regarding the status of the system, such as “00S” indicating the system is out of service or “Low Bat” indicating the battery power is about to run out of power. As another example, LED panels may be configured to display various parameters to a user such as time, date, temperature, or user's pulse.

RFID strip 96 may be disposed on top of channel bottom surface 110, with battery 102 disposed above and operably connected to RFID strip 96. Decorative cover 104 is disposed above battery 102 and, in many embodiments without a battery 102, above RFID strip 96. In some embodiments, spacers (not shown) are used to ensure RFID strip 96 and/or batter 102 remain immobilized during use. Referring to FIG. 9D an assembled jewelry piece 91 includes an RFID strip 96 and battery 102 disposed between raised edges 92, channel bottom surface 110, and decorative cover 104. Exterior surface 112 of decorative cover 104 sits flush with outer surface 108 of ring 90.

In some embodiments, a plurality of nanocapacitors may be applied to the surface of or integrated with the material forming ring 90. In some embodiments, the nanocapacitors are graphene nanocapacitors. In some embodiments, the nanocapacitors are formed as disclosed in U.S. Patent Application Publication 2013/0224394, the entirety of which is herein incorporated by reference. The nanocapacitors are configured to absorb ambient energy, such as solar energy or thermal energy from the user, and convert it to electrical energy to be used by RFID strip 96.

In each of the embodiments presented above a sealant may be used between components to create a sealed chamber containing the RFID tag. For example, in the jewelry piece 100 presented in FIG. 1, a sealant may be used between cap 2 and housing 14. As another example, a sealant may be used between the decorative cover 104 and ring 90 of jewelry piece 91 presented in FIGS. 9A, 9B, 9C, and 9D. In some embodiments, the sealant may be silicon-based, in other embodiments the sealant may be an epoxy sealer.

In some embodiments of the present disclosure, a portion or all of the exterior surface of the jewelry piece is finished with a scratch resistant coating such as certain ceramics, diamond chemical vapor deposition, or the like. Further, in some embodiments, each component disclosed above which includes at least one exterior surface of the jewelry piece is formed from ceramic, glass, gemstone, carbon fiber composite, solar cell, LED screen, diamond chemical vapor deposition, or any combination thereof.

The use of RFID tags has spread to innumerable applications, and embodiments of the present disclosure can be applied in numerous ways. In general use, a RFID tag is read by an RFID reader to transfer data on the tag to the reader. The RFID reader is operatively connected to a computer or other processing system and transfers data from the tag to the computer or processing system for use.

By way of example, RFID tags can be used in a key fob to provide keyless locking and unlocking of a vehicle door. The RFID tag enclosed in the fob uniquely identifies the key associated with a given vehicle. As a driver approaches the vehicle door, a RFID reader located in the door handle, door, or elsewhere in the vehicle reads the identifying information contained on the RFID tag. A processing system uses this identifying information to determine if the key fob is associated with the vehicle and should thus be granted access to the vehicle. If the key fob is positively associated with the vehicle, the processing system sends a signal to the vehicle door to unlock.

Additional uses of the present disclosure are included in Table 1. Table 1 assumes the implementation device (i.e.—vehicle) is equipped with a RFID reader and associated circuitry. The examples in Table 1 are provided for illustrative purposes and are in no way meant to be a full list of potential applications of the present disclosure.

TABLE 1 Applications of the Present Disclosure Keyless starting of a vehicle Arming or disarming a security system Opening, locking, or unlocking a residential or commercial door, gate, or equivalent Opening, locking, or unlocking a safe Enabling operation of a firearm Payment using credit or debit card information loaded into RFID tag Opening, locking, unlocking, or starting a personal watercraft, motorcycle, or machinery Enabling use of a cellular telephone Verifying identity at an airport or security checkpoint Verifying identity, license, insurance status, and vehicle registration during a traffic stop

The jewelry piece with interchangeable RFID tag disclosed above has several advantages. A jewelry piece provides a convenient and unobtrusive way to carry an RFID tag and is less likely than a badge, key fob, or other RFID tag carrier to be lost or damaged. By making the RFID tag interchangeable through the various means disclosed above, the jewelry piece provides a flexibility to the user to carry with them a range of information. For example, a user can have a jewelry piece with a command module containing an RFID tag loaded with identifying information specific to their professional life, i.e. containing login information for their work computer, access information to their office, etc. That same user could then switch command modules, outfitting the jewelry piece with a second command module loaded with personal information such as identifying information for specific use at a doctor's office. In various circumstances, a user could chose to limit the data they carry within their jewelry piece so as to limit the potential for fraud and identity or information theft. Command modules could also be exchanged for purely aesthetic purposes.

As yet another advantage of the invention, the jewelry piece with interchangeable RFID tag may be an entirely covert means of carrying information. As will be known to those skilled in the art, RFID transceivers and their associated circuitry are capable of securely storing a substantial amount of information. As disclosed above, this circuitry may also monitor and provide real-time information such as time, date, temperature, or user's pulse. The information contained in the RFID tag may be carried within the jewelry piece and is thus be concealed from public view.

In some embodiments, an apparatus for conveniently carrying a radio frequency identification tag comprises a jewelry piece including a threaded slot for receiving a screw post; a cap with a convex, substantially hemispherical surface and a flat surface, the flat surface connected to a housing including the screw post; a radio frequency identification tag, disposed within a buffer ring which is disposed within the housing; and wherein the housing is operatively connected to the jewelry piece by rotatably inserting the screw post in the threaded slot.

In some embodiments, an apparatus for carrying a radio frequency identification tag within a jewelry ring comprises a jewelry ring including a threaded slot; a bezel setting comprising a flat plate and a screw post, wherein the bezel setting is operatively connected to the jewelry ring by rotatably inserting the screw post into the threaded slot; a cap comprising a convex, substantially hemispherical surface and a flat surface including a recess, and wherein the flat surface is connected to the bezel setting; and a radio frequency identification tag, disposed within a buffer ring which is disposed within the recess of said cap.

In some embodiments, an apparatus for carrying a radio frequency identification tag within a jewelry ring comprises a jewelry ring including a threaded recess; a cap comprising a substantially hemispherical portion and a threaded member portion; and a radio frequency identification tag, disposed within a buffer ring, the buffer ring disposed within the threaded recess wherein the threaded recess encloses the radio frequency identification tag and the buffer ring when the cap is rotatably inserted into the threaded recess.

In some embodiments, the material of the outer cover 212 includes a plurality of nanocapacitors 213 applied to the surface of or integrated with the material forming the outer cover 212. The nanocapacitors 213 may be graphene nanocapacitors. The nanocapacitors 213 are configured to absorb ambient energy, such as solar energy or thermal energy from the user, and convert it to electrical energy. The interface 214 is disposed on an exterior of the outer cover 212 and may be located toward one side of the outer cover 212, as shown in FIGS. 10 and 11.

As shown in FIG. 10, the interface 214 has a raised portion 214 a protruding from the exterior of the outer cover 212 to an interface surface 214 b. In the shown embodiment, the interface surface 214 b is circular and the raised portion 214 a is consequently cylindrical. One with ordinary skill in the art would appreciate that the interface surface 214 b may alternatively have a variety of shapes, including a square or a rectangle. The interface 214 may be formed from a plastic, glass, or metal material.

The first side cover 216 and the second side cover 217, as shown in FIGS. 10 and 11, are annular members formed from a plastic material. In the shown embodiment, the first side cover 216 and the second side cover 217 are identically shaped.

The user inputs gestures 700 shown in FIG. 22 to the wearable electronic device 200, which can be transmitted throughout the wireless communication system 400. To input a gesture 700, the user moves a finger in various directions relative to the interface 214. As the user's finger moves over the interface 214, the user's finger is also moving relative to the plurality of capacitive plates 246 positioned within the outer cover 212 around the interface 214. As the user's finger is positioned over or moves with respect to each of the plurality of capacitive plates 246, a stored electrical energy in each capacitive plate of the plurality of capacitive plates 246 changes dependent on the relative position and movement of the user's finger. Each of the plurality of capacitive plates 246 sends a signal indicating a change in the stored electrical energy to the processor 242. The processor 242, executing software stored on the memory 244, compares the relative changes in stored electrical energy of each of the plurality of capacitive plates 246, and based on this information, determines the position and movement of the user's finger corresponding to a gesture 700. The plurality of capacitive plates 246 thus act as a capacitive touch sensor on the wearable electronic device 200.

The gestures 700 shown in FIG. 22 include tap gestures 710 and swipe gestures 720, 720′.

For the tap gestures 710, the user moves his finger only in a vertical direction and touches the interface 214. Variations in the duration of the tap and the number of consecutive taps determine the range of possible tap gestures 710. The tap gestures 710 are the same for both the substrate 240 shown in FIG. 12 and the substrate 240′ shown in FIG. 13.

For the swipe gestures 720, 720′, the user moves his finger horizontally over the interface 214 in various directions. First swipe gestures 720 are associated with the substrate 240 shown in FIG. 12. In the substrate 240, the plurality of capacitive plates 246 are arranged linearly, and the user can input a swipe left or a swipe right gesture over the interface 214. The number of consecutive swipes and combinations of left and right swipe directions determine the range of possible first swipe gestures 720. Second swipe gestures 720′ are associated with the substrate 240′ shown in FIG. 13. In the substrate 240′, the plurality of capacitive plates 246′ are arranged in a circular pattern, and the user can input a swipe left, a swipe right, a swipe up, a swipe down, a swipe diagonal up-left, a swipe diagonal up-right, a swipe diagonal down-right, and a swipe diagonal down-left over the interface 214. The number of consecutive swipes and combinations of swipe directions determine the range of possible second swipe gestures 720′.

Once the processor 242 determines which gesture 700 the user has input, the processor 242 compares the gesture 700 to a list of user-definable actions 900 for each state 1000 of the wearable electronic device 200, as shown in FIG. 24. The list of user-definable actions 900 correlated with states 1000 of the wearable electronic device 200 and gestures 700 is stored in the memory 244. The processor 242 retrieves the corresponding user-definable action 900, and controls the relevant component to execute the user-definable action 900 associated with the gesture 700 and state 1000. Exemplary user-definable actions 900 and states 1000 of the wearable electronic device 200 associated with gestures 700 will be described in greater detail below.

The wearable electronic device 200 receives notifications 800 shown in FIG. 23 from the wireless communication system 400. The notifications 800 occur at the LED 248 aligned with the interface 214. The notifications 800 can vary in color 810, number of illuminated flashes 820, and duration of each illuminated flash 830. Combinations of colors 810, number of flashes 820, and duration of flashes 830 determine the range of possible notifications 800. The notification 800 light emitted by the LED 248 illuminates at least a portion of the outer cover 212 surrounding the interface 214.

Based on signals received from the wireless communication system 400, described in greater detail below, the processor 242 compares a condition 1100 dictated by the received signals to a list of notifications 800 correlated to conditions 1100 stored in the memory 244 and shown in FIG. 25. The processor 242 retrieves the notification 800 correlated to the condition 1100 and controls the LED 248 to emit the correlated notification 800.

The use of the gestures 700 and notifications 800 within the wireless communication system 400 will now be described in greater detail with reference to FIGS. 17 and 21-25.
